So inside the rear bumper cover there is a bracket of sorts. One on the dr side, one on the pass. side. This "bracket" has three bolts two slip lower section of the quarter panel and the other bolts into the wheelwell just behind the rear tire. What is that " bracket" called?

They are called retainers. Dealer should still have them. I believe they are riveted onto the bumper cover. You could find a used set off an old bumper if someone is willing to remove them. I may have a few but time is crazy and getting over to my garage is tough. If you are unable to locate them anywhere, get back to me.
